Problem accessing cloud behind a proxy

[Davide DB]

> BTW, Davide, are you testing a binary from downloads/testing, or a binary from GitHub? Those are slightly different - but both of them should handle settings the same way... IIRC I switched the on on GitHub around to no longer link against libcurl as clearly that proxy functionality wasn't used on Windows...

These test were performed with the
subsurface-4.7.2-74-g577bf57ddfb8.exe on download/test and 4.7.4
official.

Ok so I understood correctly.

Given that I spent 99% of my time working with pc behind a company
proxy with authentication I decided to use tethering on my mobile
phone to get 4G connection just to download/upload my logbook on the
cloud.

This sound interesting...
I have several PC which are behind my company proxy with authentication.
The hack procedure is:

- disable onboard gigabit network adapter
- connect my mobile phone via USB
- enable USB tethering on my mobile phone
- Windows automagically install the new network adapter
- I test the internet connection:
--- I disable proxy use on internet explorer: direct internet connection
--- I open Chrome and successfully connect to
http://cloud.subsurface-divelog.org/ (I get the user/pwd prompt)
--- I open cmd prompt and i ping a random webisite
- I launch Subsurface from the command prompt with the -v -v prompt
(the network preferences shows No Proxy and ALL proxy fields empty)
- I still see that infamous incorrect parameter proxy error :(

PS
Just to be sure, once I disable proxy use on Internet Explorer, all my
apps that access internet and have proxy settings inside don't work.
Google Chrome inherits proxy settings from IE so it works.
Putty has its own proxy settings so it won't works.

So I don't have a system proxy I guess
